NEW DELHI – India ended 2011 amid political chaos, as the much-awaited Lokpal Bill, aimed at creating a strong, independent anti-corruption agency, collapsed amid a welter of recrimination in the parliament’s upper house, after having passed the lower house two days earlier. The episode, which leaves the bill in suspended animation until its possible revival at the next session, raises fundamental issues for Indian politics which will need to be addressed in the New Year.
